  1. Solar and Lunar Eclipse Terms • Lunar eclipse solar eclipse • Total eclipse partial eclipse

  2. How does Earth, the moon, and the sun align during a solar eclipse and lunar eclipse? • What causes solar and lunar eclipses? • Why do lunar eclipses occur only at a full moon? • Why do solar eclipses occur only at a new moon? • Why is there not a solar or lunar eclipse every month?

  3. Solar and Lunar Eclipses • A solar and lunar eclipse occurs only when the earth, moon, and sun are directly lined up. • There are two types of eclipses. • The moon goes dark during a lunar eclipse. • The sun goes dark during a solar eclipse.

  4. Lunar Eclipse • A lunar eclipse occurs when Earth passes directly between the sun and the moon. The Earth casts a shadow on the moon. • A lunar eclipse can happen only during full moon. This is because it is the only time when Earth, the sun, and the moon are directly lined up with the Earth between the moon and the sun.

  5. Lunar Eclipse

  6. Solar Eclipse • A solar eclipse occurs when the moon passes directly between the sun and Earth. The moon casts a shadow on a part of Earth’s surface. • A solar eclipse can happen only during a new moon. This is because it is the only time when Earth, the sun, and the moon are directly lined up with the moon between Earth and the sun.

  7. Solar Eclipse

  8. Solar and Lunar Eclipses • There is not a lunar or solar eclipse every month because the moon is not always on the same plane as Earth and the sun. • The moon orbits Earth at an angle. • An eclipse can be total or partial. • A total eclipse occurs when the moon or sun becomes completely covered. • A partial eclipse occurswhen the moon or sun becomes only partly covered.

  9. Quick Check Under what conditions will an eclipse take place? a. only when the sun and Earth are directly lined up b. only when the moon and Earth are directly lined up c. only when the moon, the sun, and Earth are not exactly lined up d. only when the moon, the sun, and Earth are directly lined up

  10. Quick Check What phase must the moon be in to allow for a lunar eclipse? a. new b. full c. first quarter d. waxing gibbous

  11. Quick Check Although the moon is much smaller than the sun, it looks about the same size when viewed from Earth. What fact might account for this observation? a. The moon is farther from Earth than the sun. b. Earth is closer to the sun than the moon c. The moon is closer to Earth than the sun. d. The moon shines brighter than the sun

  12. Quick Check What conditions would produce a partial eclipse of the moon? a. the moon is on the same plane as the sun and Earth b. the moon is below the plane of the sun and Earth c. the moon is far above the plane of the sun and Earth d. none of the above

  13. Quick Check When Earth’s shadow falls on the moon, the shadow causes a a. new moon. b. solar eclipse. c. full moon. d. lunar eclipse.
